Miniature valve for filling the reservoir of an apparatus for the transdermal administration of medicine

摘要

Disclosed is a miniature valve for filling the reservoir of an apparatus for the transdermal administration of a medicine comprising a) a substrate (1), b) a fuel charge (5) arranged on the substrate (1) opposite the passage to be opened through it, c) an electric resistor (2) placed in contact with the fuel charge (5) so that the supply of this resistor (2) with a predetermined electric energy ensures the combustion of the charge (5) and the opening of the passage (8'), by local rupture of said substrate (1) under the pressure of the fuel gases of the charge (5). The device is stated to be useful for filling a medicine reservoir of an apparatus for the transdermal administration of this medicine aided by inophoresis.
